holsters and the body frame or bolster, and' more particularly relates to an improved forni of truck bolster, as well as an improved structure of car body frame for use therewith,

The invention has among its objects theproduction ot a construction ot the 'kind described that is simple, convenient, efficient,l

durable, compact and satisfactory..

It has among its further objects the pro-` duction of a car construction in which the trucks may be detached from the body or attached thereto with a minimum of time and labor, and without requiring the jacking-up of the car body to an extent where the same may be warped, twisted or strained.

It has among its further objects thel 3roduction of an easier riding truck, whic in usev will have a longer life or service, as well as lengthening the serviceable life of the car body and frame. It also tends to reduce the repairs of the body or truck, owing to the easy manner in which the body is carried by the truck, without any undue stress or strains.

Other objects and advantages of the construction will appear to those skilled inthe art from the disclosures herein made.

To this end my invention consists in the novel construction, arrangement and com* bination of parts herein shown and described. and more particularly pointed out in the claims. v

It may bg4 mentioned that I have not considere itne'cessary to illustrate a ear with all the details thereof, but only'such parts as form a part of the present invention.` Neither have I considered it necessary to show with great detail and exactness parts of the structures illustrated, which in themselves form no part of the present invention,- and which may be modiedas found desirable to correspond with any particular manufacture. It may be furthermentioned that the present invention is in the nature of an improvement over the car construction shown in my U. S. Letters Patent No. 1,098,820, dated June 2, 1914.

In the present device, 1 represents the wheels of one yof the trucks, connected by the usual axles 2,` arranged to seat in any suitable bearings and carry the truck frame 3. The frame parts 3 are connected by a bolster 4, having the ends 5 arranged to be suitably carried by the end frames 3 of the truck. I have shown the bolster 4 carried by springs 6, the springs being secured in place in any of the well known manners. n addition to the springs 6, I have employed the desired number of additional springs 7, upon which the cross bolster' 4 of the truck will be additionally Vsupported in case of excessive loads or j ars and bouncing of the parts. .The springs 7 maybe termed vshock absorbers, as they substantially perform this function, and

soA

are auxiliary to the main supporting springs 6.* Arranged to be carried by the. bolster part 4 is a detachable bolster part 8, the same forming or constituting in reality a part of the truck bolster when it is seated and secured in place. This bolster part 8 1s p'rovided with an extending post or bearing member 11, which forms a center bearing or support for the car body and secures the body on the truckp The postshown 1s substantially similar to the post shown in. my prior patent mentioned. It is provided with a centrally-extending post 12, which 1s enlarged at 13 and formed with a. bearing 15 at the base, 14 being holes or the like, through which a suitable lubricant may be discharged.

The car body construction in thedevice shown consists of a pair of parallel extending channels or beams arranged centrally the car body, and provided with a bearmg member 10 at each end, which is suitably flanged and secured to the beams-in any suitable manner. Where the car body is con-l structed differently than I have shown, the part 10, or its equivalent, may, of course, be secured to any suitable part of the car or body, the arrangement illustrated being merely the preferred construction, and which I consider very desirable. l

It may be noted that the part 8 with its* upwardly extending post may be termed a T-shaped bolster part, with the leg of the T extending upwardly, that is the T is upside down or reversed. The underside and ends of the part 8 are preferably made cylindrical or semi-cylindrical in shape, as shown, land the truck or bolster part 4 provided with a substantially semicylindrical or. curved groove or recess 18 therein, in which the part 8 may rest. When positioned in the groove 18 the part 8 is secured in position and prevented from transverse movement or separation from part 4 by the locking blocks or keys 20, which are positioned under the extensions 19 formed at each end of the bolster part 4. The key 20 may be secured in position by pins 21, or equivalent means for the purpose. In the claims where I refer to one part being capable of rocking relative to the other part, I wish to be understood that either part may be considered as doing the actual rocking, the results being the same. In the construction shown in Figs. 1, 2, 4, 5 and 15, 16, the part 8 may not only be rocked onthe bolster part 4,-for example as indicated in Fig. 2, but it may alsohave a longitudinal movement or movement transversely the car,

as is indicated in the dotted lines in Fig. 15. The construction permitting this is illustrated in detail in Fig. 5, in which figure it will be noted that each end 5 of the part 4 is formed with a chamber 22 of a size to receive the'end of the part 8. The chamber is f closed, however, by a closure or partition 23', and the part 8 normally maintained in taper from one side to the a central position by an adjustable part 24, and a spring 25 arranged at each end of the part 8. The movement of the part 24 1s limited, however, by a bolt 26', or egun-'alent means, so that the same will not project from or move out of the chamber 22. The tension or strength of the spring may be as desired. An adjustment may be had by placing filling members 27 or 28 at either or both ,ends of the chamber 22, which increases the effect ofthe spring by putting it under a pressure, that is, compressing it. An additional spring may be arranged within the chamber, to act as a shock absorber in case of an unusual movement of the part 8, the same serving to reinforce the spring 25 in emergency.

In Fig. 6 I show a` slightly modified construction, in which part 23 may be adj uscll. thereby varying the effectof spring 2.3'. :1 boltor rod 26 similar to 26 being provided. rIhis construction merely illustrates another form of adjustment.

In Fig. 7 a simplified construction is shown, inwhich the end of part 8 butts against the end of wall 31 of the bolster part, the-key 20 being secured in place by pins extending through the extension 19. `With this construction, of course, part 8 has no endwise movement, but may be rocked on part 4 similar to the other constructions.

As before mentioned, in the construction shown the car is provided with centrally extending beams 9, forming a part of 'the body frame. Arranged to be carried thereby an` cross or body bolsters 33, which carry the side sills 34. There may be any desired number of cross bolsters 33, and

'the proportion and design of the same may vary :1s-found desirable. In the oonstruction shown .the bolsters 33 are formed with an under part 35, which is connected by the parts 36 to the top 33 in proximity to the beams, the arrangement being such that the parts4 substantially closely fit the beams as shown in Figs. 4, 8 and 15. The bolsters 33 may be bolted to the beams, if desired.l In addition to the bolts, however, I use locking members or binders 37. These are formed with hooked ends adapted to engage the extensions 38 on the bolsters. In Figs. 9 and 10 I show the preferred construction in more detail, in which as the members 37 are placed and drawn into position, they substantially engage with the parts 38, giving an exceedingly tight fit, as well as drawing the parts 36 against the lower flange of the beams 9. Fig. 9 shows the end 38 shown with a slight other, that is, it is wedge-shaped, so that the end 30 and lower side 38 tightly it together. As shown in Fig. 10, the endsof 38 are formed with a bend or out at an angle, as shown, at 40. When a tapering bolt 41 is employed, and

the same drawn down, the saine tends to draw the part l37 'into position, as shown in Figs. 9 and 15. The tighter the bolt is i dropped or removed. If `1t is desired to drawn down the more tightly the part 37 engages with the yends 38. Either or` both constructions may be omitted, but I prefer in most cases to embody the construction shown in Fig. 10, to which may be vadded the arrangement shown in Fig. 9, if desired. As shown in Fig. 15, lugs 42 may be provided on binders 37 to prevent the beams being drawnl together. A binder or retainer 50 of slightly different construction is shown in Fig.17, which is provided with lugs 51 and 52, arranged to space the beams, the part being bolted to the cross bolster.

In Fig. 14 I have illustrated a form of cap suitable to be mounted upon the post 12, andbear against the part 10, to lock the car body on the truck. While it is not absolutely necessary, I usually prefer kto employ it. Referring to Figs. 13 and 14, the part 43 is vformed with a flange 47, and projected downward as at 44. The same may be chambered as at 45, if desired, and provided with openings 46. chamber is toprovide the cap with a suit# able lubricant, which may work out through the vopenings 46 and thoroughly lubricate the parts. The cap may be maintained in position by a pin, or equivalent means, ex-

tended through the hole 12, or in the post 12.

The cap 43 has an additional function'. In ease the truck of the car should be entirely disabled, -any of the trucks commonly in use at the present time may be substituted by placing the cap 43 at the bottom of the bearing 10, so that the same will serve as a bearing for the usual center part of the type illustrated in dotted lines on the truck bolster 48. The part 43 may, of course, be

bolted to part 10 when seated, as shown in Q Fig. 8, similar to the construction shown in my prior patent mentioned.` If desired, king bolt 49 may also be employed.

A slightly modied locking member or key 20 is shown in Fig. 12. In this case the truck bolster 4 may be similar to any of those described, as may be the T-shapeol part 8. Thekey 20 is shown, however, formed with anges 50 and 51, arranged to engagey wit-h the sides of the extension 19 and the bolster 4 respectively.

In case it is desired to remove the truck from the car body, the body of the car is jacked up only su'lliciently to take all weight or pressure oli of the truck, but need not be Isuilicient to lift the body off of the part. In other words.I it is only necessary to jack the same up suiiciently to relieve the weight on the springs of the truck. The pins 21,

` or their equivalents, may then be removedv The purpose of they the end of thecar. The pin 12 may then be removed, whereupon the part 8. may be be rocked as indicated in Fig. 2, it being immaterial Vas to which rocks, and in fact both may rock at the samev time. With the constructions illustratedin Figs. 15 and 16, the body and ytruck are also relatively adjustable transversely the car. The result is that on an extremely rough roadbed, or a roadbed with many curves, or where a vload of freight is. carried, which ,is 4not evenly distributed throughout the car, or

` may shift and rock, the cai-'body at all times rides easily and with a minimum of vibration andshocks. It will be noted that with the construction the usual side bearings on the trucks are unnecessary and may be doneh away with, although` they may be .used if preferred.

Having thus described my invention, 4it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limitingmyself to the "exact form, construction, arrangement or combination of parts herein shown and described, or uses mentioned.
